The spot received a "pants on fire" rating from a fact-checking website.

Donald Trump launched his first TV ad for his GOP presidential bid on Monday and hours after it was released, the spot was being criticized for being disingenuous.

About 22-seconds into the ad, footage is shown of people running toward a border. During the scene, the voiceover says, "He'll stop illegal immigration by building a wall on our southern border that Mexico will pay for."

Turns out, the footage actually shows Moroccans crossing the border into Melilla, according to Politifact. The independent fact-checking journalism website gave the footage a rating of "pants on fire."

Trump spokeswoman Hope Hicks told Politifact she was not aware of the source of the footage in the ad.

A request for additional information from the Trump camp was not immediately returned.
